A review is presented of the design and performance of an electro-optical scanning system for direct transfer of raster data to recording media. The system uses either a semiconductor laser diode or a HeNe laser to record rasterized bit map images, and features a grating clock scheme for exact beam positioning at high speed, high resolution, and extremely small cross scan error.
